Clinical diagnosis and treatment of asparaginase associated pancreatitis in adults / 中华胰腺病杂志

ABSTRACT

Objective To investigate the clinical characteristics and the course of diagnosis and therapy of asparaginase associated pancreatitis (AAP) in adults, in order to improve the ability of diagnosis and treatment.Methods Data of 384 cases of acute lymphoblastic leukemia (ALL) who received treatment in Department of Hematology, Zhejiang Hospital, and Department of Hematology, Second Hospital Affiliated to Wenzhou Medical University from January 2009 to June 2015 was retrospectively analyzed.All patients were given multi-drug chemotherapy including PEG-asparaginase or L-asparaginase, the incidence of AAP, clinical manifestations, diagnosis, treatment and prognosis were analyzed.Results Among the 384 cases, 18 patients developed AAP, and the incidence of AAP was 4.7％, including 13 cases of mild AAP (MAAP), 5 cases of severe AAP (SAAP).Sixteen cases of AAP occurred during the induction-remission treatment phase, 2 cases during the maintenance-intensification phase.The major manifestations of AAP were abdominal pain, and increased serum amylase and lipase.After treatment, abdominal pain of MAAP patients alleviated, serum amylase and lipase obviously decreased, and re-use of PEG-Asparaginase or L-Asparaginase was not associated with the recurrence of AP.Levels of serum amylase and lipase in 5 cases of SAAP repeatedly increased, 1 case died of severe infection, cyst rupture and hemorrhage.Conclusions Adults patients with ALL present with abdominal pain during chemotherapy of aspargase should consider the possibility of AAP, the measurement of serum amylase and serum lipase should be strengthened, in addition, ultrasound and CT scanning may be helpful for early diagnosis and treatment of AAP, and improve the prognosis.
